I have literally started tracking being social as a habit on an app for the last few months and it has been a godsend. Every day, if I do something social, I put a tick in my app.

At first it was just to get over my social fears, but now as I get more comfortable, I still keep doing it because I love the rush of talking to new people and seeing if we click.

And of course, the fear never completely goes away in all situations, but it turns into something exhilarating, like before an important test/interview even when you're well prepared.
